“WE SEE COLLABORATION WITH OUR CLIENTS AND THE SECTOR AS A WHOLE AS ESSENTIAL TO FINDING THE SOLUTIONS TO REDUCE EMISSIONS OF THE WORKS WE DO”

the main engines of the hopper dredger Shoalway. Alongside the use of a SCR Catalysator, the testing concluded that reductions of up to 90% are achievable for NOx and particulate matter, and in some cases a slightly better fuel consumption is possible. If the engine also runs on a Biofuel blend, the emission reduction possibilities are extended even further. DELIVERING ON THE 2020 SULFUR CAP With regard to sulfur emissions, new IMO regulations (MARPOL Annex VI) entered into force on January 1st, 2020. This requires that from that date, sulfur content in the fuel used for international shipping must be limited globally to 0.5%, compared with the previous standard of 3.5%, in order to minimize emissions of sulfur oxides from ships. Boskalis switched to low-sulfur fuels (Marine Gas Oil) in the fourth quarter of 2019. This will have positive impacts not only in terms of sulfur oxides but also lower carbon emissions.

Energy-efficient offices and warehouses help us to further reduce our CO 2 footprint. In line with the targets of the EU Energy Efficiency Directive, we aim to have energy-neutral offices and warehouses in the EU by 2050. To help us progress towards our Netherlands business CO 2 reduction ambition of 35% by 2022, we will install 5,600 solar panels on our newly built sustainable central distribution center for internal clients in Vlaardingen in the Netherlands. These panels will produce around 1.8 million kWh per year – enough for 500 households. Alongside this solar energy facility, we have improved the energy efficiency of the building itself, resulting in a carbon negative site. Overall, this represents 15% of Boskalis’ electricity needs in the Netherlands and additional sites for more solar energy are being considered.
